[Solved] Improving and Optimizing Code

Hello, Dcrew here! I have this:

The code makes it so that if the player is under a tree then the tree is half visible (50 opacity).. and if not then the tree is fully visible. Now as you see in that code I use a for each loop. and wondered if there was a way that uses less memory. it's not bad (it runs fine) but I'm guessing with my code that I used if I had like 50+ tree's then it would get laggy.. Is there another ray of hope? Or will an update make a better way?

Player overlapping tree = opacity 50

Player overlaping tree [negated] = opacity 100

???

Player overlapping tree = opacity 50

Player not overlapping tree = opacity 100

Yes, How is that humanly possibly difficult to understand? -.-

Edit: Oh I realise your suggesting code, I don't know if that would work because wouldn't you need to check each tree object with a For Each?

Edit 2: I'm a fruit!! It worked:
